Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation . [ 1 ] IgG molecules are created and released by plasma B cells .
Also at first, the mature B cell expresses membrane-bound IgD and IgM. These two classes could switch to secretory IgD and IgM during the processing of mRNAs. Finally, further class switching follows as the cell keep dividing and differentiating. For instance, IgM switches to IgG which switches to IgA that eventually switches to IgE
[2] [16] Among the many functions of C1q, C1q triggers clearance of immune complexes and apoptotic cells by activating the classical pathway and binding directly onto phagocytes. [ 1 ] [ 17 ] Consequently, systemic lupus erythematosus from insufficient amounts of C1q is characterized by the accumulation of autoantibodies and apoptotic cells. [ 4 ]
These cells are defined by the absence of antigen-specific B-or T-cell receptor (TCR) because of the lack of recombination activating gene. ILCs do not express myeloid or dendritic cell markers. [40] Natural killer cells (NK cells) are lymphocytes and a component of the innate immune system that does not directly attack invading microbes. [41]
IgG immune complexes are the ligand for these receptors and immune complex binding to these receptors induces apoptosis, or cell death. After B cells are activated, they differentiate into plasma cells and cease to express BCR but continue to express FcγRIIb, which allows IgG immune complexes to regulate IgG production via negative feedback ...
Mechanism of class-switch recombination that allows isotype switching in activated B cells. Immunoglobulin class switching, also known as isotype switching, isotypic commutation or class-switch recombination (CSR), is a biological mechanism that changes a B cell's production of immunoglobulin from one type to another, such as from the isotype IgM to the isotype IgG. [1]
It has the ability to bind to all 4 human IgG subtypes: IgG1, IgG2, IgG3, and IgG4. [7] Anti-Human IgG [8E11] This is a recombinant monoclonal antibody to human IgG. However, it can screen for IgG in nonhuman primates including vervets, chimpanzees, and mangabeys. The anti-antibody can distinguish between human and nonhuman IgG. [8]
The fragment crystallizable region (Fc region) is the tail region of an antibody that interacts with cell surface receptors called Fc receptors and some proteins of the complement system. This region allows antibodies to activate the immune system, for example, through binding to Fc receptors.
